My invention consists in new and useful improvements'in angle iron derricks, skeleton .jointswhioh will securely clamp the adjacent leg sections and grits of thederrick at their points of intersection, both at the extremities 10 of the derrick, and intermediate thereof.

' Another object. of1iny invention is toprovide a joint of the above character. whichwill not only secure the members of a skeleton tional support tothe same. i

A still further object of my invention is to provide a joint and clampingmeans, which my invention consists maybe employed on derricks-equipped with additional angle iron supporting legs. or relegs.

which will appear as the description proceeds,

herein set forth, illustrated in the accompanying drawings, andfinore particul pointed out in the appendedclaim's. g V

Referring to the drawings, 1 represents the base upon which the derrick is supported, 2 and 3 designate sections of the common leg'of the derrick, 4 and .5, sections of thereleg or ,With the above and other olojectsinview in the novel features f arly substantially ofconventional type. 8 represents the outer clamping plate of the lar plate of suitable metal provided with two inwardly projecting lugs9 and 10, arranged ,interposed between the upright members are common leg ijoint,,which comprises an angu-' on the inner surface,=thereo;f toward the upperextremityofeach arm of the angle. At

each of the four corners of thisangular plate 8,-I'provide a key hole slot 11, adapted to. receive and grip the ends of thebracerods 12, ashereinafterset forth. The central portion of the plate 8is cut outand bent inwardregister with vertical slots 14, in the upper edge of the, lower. section 2 of the common leg of the derrick, asclearly shown -'in Figs. 2 fland3..fl:,;-

15 representstheinner clamping plate of the-.jioint, which is also {angularin shape and 1,6. and; 17,,oii theverticahedges thereof, said arms being braced by a rod 23 which may be; integraltherewith,or secured thereto in any suitable manner. The central portion of the plate 15. is cut out'as at 18: to receive the ear "13 on. the outer clamping plate 8, as hereinafter set forth. The leg engaging face of the I inner clampingplate 15 is provided along its vertical edgesnear the up'per'andlower extremities thereof, with projecting lugs 19,20, 212116122, the lugs 19 and 20'being adapted to register with-recesses 19 and 20" respectively, in: the lower portion of the upper section 3-- ofthe' derrick leg, while the lugs 21 and 22 are adapted to register with, the recesses 21 and-22wrespectively, in the-upper portion .ofthejlower section 2 of the derrick. leg, when the clamps are in place as clearly shown in Fig; I of the drawings. 1 The horizontal arms 16 and '17 of the inner clampingplate 15'are provided along the lowl er .edges of their'e'ngaging faces,withlprojectinglugs 24 and 25, adapted to register 1y to-form a U-shaped car 13. adapted to i provided with horizontal projections or arms lower edge of thefhorizontal girts 6:and 7, -wherr theydevi'ce assembled. 1i 26 represents a wedgekey, which is in serted in the U-shaped car 13 when the parts are assembled as shown in Fig. 1, to secure 'the clamping plates 8 and tightly together.

7 As before stated, the releg or supporting leg is composed of sections 4 and 5. These sections are provided on their adjacent edges with vertical slots 27, 28, 29 and as clearly shown in the disassembled view in Fig. 3.

31 represents an angular connecting mem-..

ber provided with step-shaped arms, adapted to register with said lugs 27,28, 29i'and"30'" to secure said releg sections against lateral I movement.

32 represents a temporary; releg' clamp adapted to be used while the device is being assembled. This clamp comprisesa V-sha-ped lug 33', each leg of which is apertured longitudinally tofreceive the straightthreaded end of hook members 34 and'35, which hook members engage-the edges of the common leg and-releg of the derrick, as shown in Fig- 1,'to retain thesame in place., The hooks -34: and 35 are adjustable by means of nuts 36 on the straight ends thereof.

The assembly of my improvedderrick is as follows: 1 r V Y The lowersection 2 of the common leg, :is secured in place upon the base support l, by means of bolts 1, or any other suitable means. Theouter clamping plate 8 is then applied to the outer face of the section 2, the 1 U-shaped ear 13 engaging the vertical slots L14E'in theupper edge of said section 2, and I theupper section 30f the common legis applied immediately above the section 2, its

lower edge abutting the upper'edges of the U-shaped ear 13, and leg section 2, as clearly :shown in Fig. 2. Theangle iron girts 6 and? are then placed oneithersideof section2 of the derrick leg, with the vertical face of each angle adjacent the inner face of the clamping plate 8, the upper. edges abutting theunder surfaces of the'lugs 9-and 10. The inner clamping plate 15 is then applied to the inner surface of the common leg sections 2 and 3, the lateral arms 16 and 17 engaging the lower surfaces of the horiizontal angle of the girts 6 and 7 to support the. same while the lugs 24 and25 on said armsregister with the recesses 24 and 25',

respectively, in the vertical portions of said girts." The lugs 19'and 20 on the inner'clamp ingplate 15 engage the recessesl9 and 20' respectively, in the upper section 3 of the common leg, and the lugs 2 1'and22' engage gtherecesses 21 and 22. respectively, in the lower section 20f the common leg, while the 'U-shaped ear 13 of the outer plate Spasses through the aperture 18 in the central'portion of the inner clamping, plate 15, to permit the wedge key 26 to be'passed therethrough to secure the elements in place The -releg or-reinforcing leg may now be applied as followszThe lower/section e of ,the releg is mounted and secured inplace ,of,, oeng aging the projecting portion of the "connecting"member 31. After this section in its place, and while the remainder of the sections of the releg are being assembled, r-the temporary;clamp 32 is slipped over the vertical edges of the common leg, andthe releg sections, as-shown in Fig. 1, andthe nuts 36 tightened to retain the members in place during thecompletion of the assembly.

The brace rods 12, havingangularly' dis- "posed enlarged heads12a, are secured in place" on the outer clamping plate 8, said enlarged heads 12a'engaging the key hole slots 11 in said plate From the foregoing, it is believed that the operation construction and advantages'of my invention may be readily understood by those skilled in the art' without further'description, 1t beingborne in mind that numerous changes maybe made in the details disclosed without departing from the spirit of the in vention, as expressed in the claims.

What I claim and'desire "ters Patent is: r a L Y s j 1. Ina derrick, leg sections-and girts having an interlocked connecting member,-comto secure' by Letprising inner and outerclamping parts, re-

cesses at predetermined-points in said "leg sectionsand girts, lugs on the adjacent faces '-.of said clamping parts, adaptedto engage and lnterlock-with said recesses, and means said interlocked relation. i a

2'. Ina'derrick, leg sections and girts havng an interlocked connecting'member, comfor securing'said clamping parts together in prising inner and outer .V-shaped clamping parts," recesses at predeterminedpoints in said leg sections and girts, lugs on the adacent faces of said'clamping parts, adapted 'to engage and interlock with said recesses,

and means for securing saldclamping parts together in said interlocked relation, comprising an apertured car on one "of'said clamping parts, adapted, to. extend through an opening in the other part, one of .said leg sections being provided 1 with 7 vertical 's'lots at the joint end, adapted to receive said ear, and a wedge key for engagi'ng'theaperture in said ear to secure theclamping parts together.

3. In a gle-leg sections, vertical slotsin the adjacent horizontal edges of each of said sections, and a common connecting member comprising a central angular portion, each end of which projects outwardlyin a flange, awing derrick, a plurality of abutting an ii on the end of each flangelying parallel to the respective arm of said angular portion, the adjacent vertical slots in said sections being adapted to engage said flanges with said angular portion lying against the inner surface of the leg section and the Wings 1ying against the outer surface.

In testimony whereof I aflix my signature.
